Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a view showing an embodiment of a system for automatically generating lists according to the present invention, which shows a case where the present invention is applied to a data read-only system.

Referring to the drawings, the list automatic generation system includes a control unit 20, a disk engine 21, an input unit 28, a display unit 30, and a playback unit 32.

The control unit 20 controls each component of the list automatic generation system, receives and processes data from each component, or transmits the processed data to a predetermined component. In particular, the control unit 20 receives data from the disk 22 inserted into the disk engine 21 by controlling a controller (not shown) mounted in the disk engine 21. Here, the control unit 20 is preferably composed of a DSP (Digital Signal Processing) circuit in order to increase the accuracy and reliability of digital communication.

In addition, the control unit 20 counts the number of selections for the files selected by the user among the files recorded on the disk 22, accumulates the counted values, and includes a nonvolatile memory provided in the disk engine 21. It is stored in (26).

The disk engine 21 includes a volatile memory 24 and a nonvolatile memory 26, and records the data recorded on the disk 22 inserted into the disk engine 21, the volatile memory 24 and the nonvolatile memory ( Data stored in 26 is transmitted to the control unit 20. Here, the disc 22 represents a storage medium that records only read-only data. The disk 22 records data in file units and stores attributes for each file. The attributes of each file stored in the disk 22 include the name of each file, the size of each file, the content summary of each file, and the like. Here, the disk 22 inserted into the disk engine 21 has a unique ID (ID: identity), so that the control unit 20 can recognize the attributes of each of the inserted disk 22. It is preferred to be implemented.

When the disk 22 is inserted into the disk engine 21, the volatile memory 24 receives and stores attribute information among attributes of files recorded on the inserted disk 22. Here, it is preferable that the attribute of the files received by the volatile memory 24 from the disk 22 include the name of each file, and the list of the names of each file becomes the entire list. The information received by the volatile memory 24 is used to enable the user to quickly detect desired information from the disk 22 in which a large amount of data is recorded.

The nonvolatile memory 26 receives a name of a file selected by a user among attributes of files recorded on the disk 22, and receives and stores a counting value of a file selected by the user from the controller 20. do. The names of the selected files are listed in order according to the size of the counting cumulative value of each file, which makes a ranking list.

Here, the volatile memory 24 temporarily stores the attributes of the files recorded on the inserted disk 22, whereas the nonvolatile memory 26 is the disk 22 that has been inserted at least once into the disk engine 21. The attribute for and the attributes for files that have been played back at least once from the disc 22 are continuously stored.

The input unit 28 is implemented with keys, cursors, and the like so that a user can select a desired file from among files stored in the disk 22.

The display unit 30 provides a list of attributes of files stored in the volatile memory 24 or the nonvolatile memory 26 so that a user can quickly find a desired file among the files stored in the disk 22.

The reproduction unit 32 reproduces the file selected by the input unit 28. Here, the playback unit 32 includes a monitor, a liquid crystal display (LCD), a speaker, and the like according to a system for reproducing the selected file.

Next, a list automatic creation process performed by the list automatic creation system having the above configuration will be described.

FIG. 2 is a flowchart illustrating a list creation process performed by a system having the configuration as shown in FIG. 1.

Referring to the figure, the user inserts a disk 22 including a file for playback into the disk engine 21 (S401). When the disk 22 is inserted into the disk engine 21, the controller (not shown) included in the disk engine 21 displays the attributes of the files recorded on the disk 22 in the volatile memory mounted on the disk engine 21. To (24). The attributes of the files include a complete list of the files recorded on the disk 22, and may further include a summary of file contents, a file size, and the like, depending on the size of the volatile memory 24. In addition, the controller provided in the disk engine 21 causes the controller 20 to recognize that the disk 22 is inserted.

When the controller 20 recognizes that the disk 22 is inserted through the controller, the controller 20 checks the unique identification code given to the disk 22 and counts the number of times the disk 22 is inserted (S403). In addition, the controller 20 determines whether the number of times the counted disk 22 is inserted is greater than a predetermined value. For example, the controller 20 determines whether the number of times the disk 22 is inserted is greater than 1 (S405), and when the disk 22 is not inserted for the first time, the disk 22 automatically starts from the nonvolatile memory 26. It may be implemented to receive a rank list of files stored in. The control unit 20 provides the display unit 30 with the ranking list received from the nonvolatile memory 26, and displays the ranking list in step S407. Here, the user may be implemented to change the mode of the rank list mode displayed on the display unit 30 to the full list mode through the input unit 28 (S409).

The user selects a desired file name from the ranking list displayed on the display unit 30 (S411). 3 is a diagram illustrating an example of the display unit 30 according to the present invention, and illustrates a case where a rank list is displayed. As shown in the figure, when a list of predetermined files is displayed, the user selects the predetermined files in the list through the input unit 28. When a predetermined file is selected by the user, the control unit 20 fetches data of the selected file from the disc 22 and provides the extracted data to the reproduction unit 32. The reproduction unit 32 reproduces the data for the file received from the control unit 20.

When the number of times the disk 22 is inserted is not greater than a predetermined value For example, when the disk 22 is first inserted into the disk engine 21, the entire list of files stored on the disk 22 from the volatile memory 24 automatically. It can be implemented to receive. The control unit 20 provides the display unit 30 with a full list received from the volatile memory 24, and displays the full list mode (S415). Here, the user may be implemented to change the mode of the entire list mode displayed on the display unit 30 to the rank list mode through the input unit 28 (S417).

The user selects a desired file name from the ranking list displayed on the display unit 30 (S419). When a predetermined file is selected by the user, the control unit 20 fetches data of the selected file from the disc 22 and provides the extracted data to the reproduction unit 32. The reproduction unit 32 reproduces the data for the file received from the control unit 20.

If a predetermined file is selected by the user from the file list in the rank list mode or the full list mode, the control unit 20 displays the attribute information on the file selected in the nonvolatile memory 26, that is, the file name and the number of times of the selected file. Search for the cumulative value of. If there is attribute information of the selected file in the nonvolatile memory 26, the control unit 20 increases the counted cumulative value for the file by 1 (S413), and updates the accumulated cumulative value to the nonvolatile memory 26. Save it to If there is no attribute information for the selected file in the nonvolatile memory 26, the controller 20 adds attribute information for the file and stores the attribute information in the nonvolatile memory 26.

In addition, the controller 20 compares an increased cumulative value of the selected file with a cumulative value of other files stored in the nonvolatile memory 26 (S421). The control unit 20 rearranges the names of the files in the order of the cumulative values when there is a change in the order of the cumulative values of the respective files (S423), and the names of the rearranged files in the nonvolatile memory ( 26). In this manner, the rank list stored in the nonvolatile memory 26 is updated with a new rank list (S425). If there is no change in the order of the cumulative value of each file, the rank list of each file is maintained (S427). Thus, the automatic list generation method according to the present invention ends. In such a method of automatically creating a rank list of the inserted disc 22, the identification code of the inserted disc 22 is confirmed, and a ranking list unique to the disc 22 corresponding to the identification code is created. Therefore, even if several disks 22 are alternately inserted, the user can manage the files recorded on each disk 22, respectively.

Here, the nonvolatile memory 26 is configured to store the names of the selected files in order according to the cumulative value size of the number of times of selection of the files. However, the present invention is not limited thereto, and the nonvolatile memory 26 may store the names and the cumulative values of the files in a non-ordered order and arrange and display them in order when the control unit 20 displays them on the display unit 30. It may be.

FIG. 4 is a diagram illustrating another embodiment of FIG. 1 and illustrates a case where the present invention is applied to a system capable of reading and writing data. Such ones are, for example, DCD. Here, the same member numbers are assigned to the same members as in FIG. 1.

Referring to the drawings, the list automatic generation system includes a control unit 20, a disk engine 21, an input unit 28, a display unit 30, and a playback unit 32.

The control unit 20 controls each component of the list automatic generation system, receives and processes data from each component, or transmits the processed data to a predetermined component. In addition, the control unit 20 counts the number of selections for the files selected by the user among the files recorded in the data area 22a of the disk 22, and accumulates the counted values to list the disk 22. In the area 22b.

The disk engine 21 includes a volatile memory 24, and transmits data recorded in the disk 22 inserted into the disk engine 21 and data stored in the volatile memory 24 to the control unit 20. Here, the disk 22 represents a storage medium that can be read and written.

The data area 22a of the disk 22 stores data in file units. In addition, the list area 22b of the disk 22 stores the name of the file selected by the user among the files recorded in the data area 22a of the disk 22 and the counting accumulated value for the selected file. The names of the selected files are listed in order according to the size of each file's counting cumulative value, which forms a ranking list.

Hereinafter, in a system capable of reading and writing, the structure and operation of the list area 22b provided in the disk 22 are different from those of the nonvolatile memory 26 (see FIG. 1) in the read-only system. Since the same, the description is omitted.

According to the present invention, by automatically generating a list of files according to the size of the number of selections by comparing the number of selections for the files frequently used by the user, the user can easily distinguish and use the frequently used files and the unused files. For files that do not exist, separate management such as deletion or separation can be performed.
